Improvement in scrubbing-brushes



BENJAMIN e. EITZHUGII, 0E FREDERICK, MARYLAND.

IMPROVEMENT IN SCRUBBING-BRUSHES.

Speciication forming part of Letters Patent No. 131,674, dated September24, 1872.

To all whom 'it may concern:

Be it known that I, BENJAMIN G. FITZ- HUGH, of the city and county ofFrederick and State of Maryland, have invented a new and 'usefulImprovement in Scrubbing-Brushes, of which the following is aspeciiication:

My invention relates to scrubbing-brushes having an India-rubberscrubbing-surface; and my said invention consists in combining a tubularrubber-scrubber with an interior clamping-bar and a locking device, in amanner to allow the said tubular rubber, when onevside is worn out, tobe turned upon its `clamping-bar to present new scrubbing-surperspectiveviews of the separate parts detached.

The end of a handle, a, passes into a socket, b, formed on across-piece, c, the ends of which are slotted, as shown at d and d. Thiscross-piece c is curved longitudinally, so as to form a shield for andconform to the shape of an India-rubber tube, e, which is' held againstthe concave under side of the piece c, by `means of a metal bar, f, theends of which are provided with holes y, into which holes the ends of aspring-rod `or bow, h, are hooked, which spring-rod, being passed over apin or knob, fi, on the handle, holds all the parts irmly to each other,the bar f holding the tube e against supporting-shield o, and thespringrod h holding the bar f and pieces c with its socket b to thehandles.

If one portion of the tube e has been used up by scrubbing, thespring-rod h is released from the knob i on the handle, therebyreleasing the pressureof the bar j' against the tube e and piece c. Thetube e can now be freely revolved to bring a fresh portion of itssurface in position to serve as a scrubbing-surface, and the parts fixedfirmly in place again by replacing the spring-rod over the knob e' onthe handle. Y

If it is desired to replace the used-up tube e by a new one, thespring-rod h is released from the knob i, the piece c moved endwise, thelarger slot d permitting the other slot to free itself from the rod h,whereby the piece c, with the handle, can be removed from the otherparts. the bar f, and the bar removed from the tube and slipped into4the new tube, and the parts put together, as already described. Thespace between the .lower end of the tube e and the under side of the barf allows a certain elastic play to the scrubbing portion of the surfaceof the tube, thereby enabling it to adapt itself to the inequalities ofthe surface to be scrubbed, and thereby doing better execution.

If one portion of the scrubbing-surface is used up a new one can bepresented in a moment and without any trouble.

Having described my invention, I claimf l. A tubular .rubber-scrubber,in combina- -tion With the interior clamping-bar and the locking device,to allow the tubular rubber to be turned when one side is worn out, topresent a new unworn side for use, as described.

2. rlhe combination ofthe India-rubber tube e, bar f, spring-rod h,slotted cross-piece c with its socket b, and handle a provided with aknob, i, all arranged to operate as av scrub'4 bmg-brush, essentially asdescribed.
